msm: cpp: Reduce CPP timeout in case of hardware delay



If CPP driver does not receive interrupt from the
microcontroller for 300ms it resets IRQs and loads
firmware to the microcontroller again. In this period
some frames provided by VFE may be lost. To avoid
frame loss the timeout is set to 50ms.
